I'd do just what you said in your post. I really would. I think it'd help a lot.

I am going to be telling my pdoc at my next appointment that I want a re-evaluation of sorts. He told me it's possible it might not be BP for me so I'm going to ask him if it's possible to check into other possibilities.

But yes. Just tell them that you want a second opinion. If you've known them for a few years, I'm sure they won't be offended. Their job is to help you and if you think that you want a different opinion to help you feel better, they should understand that.

Good luck!
